Abstract

The invention relates to a method for the computer-assisted analysis of the reliability of a technical system comprising a plurality of technical components (Bl, B2, B3). According to said method, the reliabilities of the components (Bl, B2, B3) are respectively described by a component function (f1(t, t1), f2 (t, t2), f3 (t, t3) ) that depends on at least one parameter (t) and a parameter interval (t1, t2, t3) of the at least one parameter (t), which is associated with the components (Bl, B2, B3) and influences the reliability of the components; a system reliability (F (t, tl, t2, t3) ) of the technical system is determined from the reliabilities of the components (Bl, B2, B3); a variation value (d/dtl F(t, tl, t2, t3), d/dt2 F(t, tl, t2, t3), d/dt3 F(t, tl, t2, t3) ) is respectively determined for at least some of the components f& (Bl, B2, B3), constituting a value for the variation of the system reliability (F (t, tl, t2, t3) ) according to the variation of the parameter interval (tl, t2, t3) of the respective component; and an influence quantity relating to the influence of the respective components (Bl, B2, B3) on the system reliability (F(t, tl, t2, t3)) is respectively determined for at least some of the components from the variation value (d/dtl F(t, tl, t2, t3), d/dt2 F(t, tl, t2, t3), d/dt3 F(t, tl, t2, t3) ).
